A definite, "Yes, but!" would be my response.

"But there are numerous examples of citizen science projects recording less charismatic taxa ... "

One example of a change sliding in under the radar may be that of Purple Swamphens. My farmer neighbour used to say that he had 300 of them and they ate the same as five cows. At that time I could never count more than sixty. Last month we were chatting over the fence and he commented that there were now only about fifty. I could count less than twenty at the time and have just counted 18 but know I missed one young one and its parent; so say 20.

Yesterday I was at a friends place near the water on Tinaroo Dam and she asked where have all the Swamphens gone? There used to be many between her house and the lake and they would raid her garden every day. None were to be seen and none had been seen for some months. Her husband added that he had not seen them along the roads where they cross creek lines either and I didn't on my return home either.
